SPEGIEICAFLION forming part of Letters Patent No. 702,540, dated June 17, 1902.

- 1 5 Application filed November 18,19Q1. ;Se'rial No. 82,705. (No model-) To all whom, it ea concern; s V Be it kDOWD' th at WQ- JZMES W.CLARK and ELMER A. CLARK," citizens of the Uf 'it'ed States, residing at Janesville, in the-county of Rock and State of Wisconsin, have invented certain new, and. usefuliImprovements in the following to be'a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. I

This invention relates totheltypi of chairs having the back and seat adjustable to suit the convenience and comfort of the user and aims to provide simple, effective, and novel means for simultaneous adjustment of the back andseat and securing them in an ad-" justed position." v For a full description ofthe inventiona'nd' the merits thereof andralsoito acquire a knowledge of the details of iconstruction of the means for effecting thej-resultj reference is to be had to the following-descriptionand drawings hereto attached; i

While the essential and charaetferistiqfea; tures of the invention'are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying; drawings, in which V Figure 1 is a verticalsectiou of achair embodying the invention. Fig."2 is a top View thereof, parts being brokenawayj'.

Corresponding and like'par'ts are "referred. to in the following description and indicated in both views of the drawings by-the same reference characters. A 7 I The frame of the chair miay beofany construction and, as shown,;. comprises legs 1, cross-pieces 2, 3, and 4,-anda'n ar'm-rest 5 at each side. The ertsspieces 3 and dare slats and are. spaced apart and arearranged about: parallel with the seat 6.1 1 A slide7 is supported by means of the cross-pieces 3 -and 4 in such a mannerasjtoanove forward and backward, said-slide-beingin the form of a bar having its ends forked so as to embrace the upper and lower sides of 'therespective crosspieces 3'and 4..

The back S'is'pivO'tednearits lower end to the frame, as shown at 9, and its side bars have their lower ends connected by a bail 10 with the slide 7, the extremities of the bail being journaled in the extensions of the side fbaI'S of theiback and the central portion of the bail beingijournale'd to the slide '7. A springll connects the slide 7 with a crossbar 12 at the rear of the frame and serves to hold the slide and back in a given position. The upper rear portion of the slide is inclined, as shown at 13,{and forms a support for the rear portion of the seat 6. Hence the inclination of said seat is governed by the position of 'the'slide7withreferencetotheframe. Ablock for cross-piece 14 is provided at thebottom side of the seat 6 and restsupon the incline 13 and rides thereon as the slide 7 is'movcd'forward and backward, so as to cause the rear'portion of thejseat either to fall or rise. A series of cog-teeth '15 is provided at the upper side of w the slide, 7, near its front end, and a pawl 16 cooperates therewith to hold the slide 7 in an adjusted position, said pawl being loosely connected at '17 to the front cross-piece 2 of the frame. A bar 18 extends transversely-of the, frame and comes beneath the pawl 16 and is adapted to disengage said pawl from theco -teeth to admit of the slide 7 being moved by the application of force to the back 8.' ,This bar 18 is pivoted atone end to the cross-piece 3, as shown at 19, and its opposite end has a vertical rod connected thereto and extended within convenient reach of the occupant of the chair, so that the pawl may be operated Without requiring the personrising from or leaving the chair.

The parts being arranged substantially as shown, the back is held in an adjusted position by engagement of the pawl 16 with a selected tooth 15 of the slide 7. When it isrequired to change the inclination of the back of the chair, the rod 20 is drawn upward, thereby disengaging the pawl 16 from the ate'oth of the slide 7, after which the back may be moved either forward or rearward to the desired position and is secured by releasing therod 20, which permits the pawl-16to engage withva tooth of theslid e 7. 7 The seat 6 being pivoted nearerits frontend, as shown at 21, normally tends to gravitateat its rear end, and the incline o'rfcam 13, acting as a wedge, causes the rear portion of the seat either to rise or fall, according to the position of the back and the relative location of the slide 7. When the back of the chairis pressed rearward at its upper end and it is required to have it assume a normal position, it is only necessary to pull upward on the rod 20, which efiects a release of the slide 7 and permits the spring 11 to contract and return the parts to a normal position, as will be readily understood.

Having thus described the invention, what is claimed as new is- 1. In a chair, the combination with the frame comprising spaced cross-pieces and the back pivoted thereto, a slide embracing opposite sides of the said cross-pieces and connected with the chair-back and provided with cog-teeth, and a pawl connected with the frame and adapted to cooperate with the said teeth to secure the slide and chair-back in a given position, substantially as specified.

2. In a chair, the combination with the frame, a pivoted hack, a vertically-adjustable seat, a slide mounted for rectilinear movement and connected with the said back for simultaneous action therewith and having an inclined portion upon which the seat rests to move up or down as the slide is shifted either forward or backward, and means cooperating with the slide to hold it and the seat and back in an adjusted position, substantially as specifled.

In testimony whereof we afiix our signatures in presence of two witnesses.
